Response Format:
Bits [31:0] are sticky and will not be reset by a Link Reset or a Codec Reset:
6.12.6 Digital Mic In 2 Configuration Default
The Configuration Default register is used by software as an aid in determining the configuration of jacks
and devices attached to the codec. At the time the codec is first powered on, this register is internally load-
ed with default values indicating the typical system use of this particular pin/jack. After this initial loading,
it is completely codec opaque, and its state, including any software writes into the register, must be pre-
served across reset events such as Link Reset or Codec Reset (the Function Reset Verb). Its state need
not be preserved across power level changes.

Bits Type Default Description
31:30 Read/Write 10b
Port Connectivity (PCON): The port complex is
connected to a fixed function device.
29:24 Read/Write 110111b
Location (LOC): This field indicates the physical
location of the jack or device to which the pin
complex is connected. Set to Other | Mobile Lid-
Inside.
23:20 Read/Write Dh
Default Device (DD): Indicates the intended use
of the connection is for Digital In.
19:16 Read/Write 6h
Connection Type (CTYP): Indicates the type of
physical connection is Other Digital.
15:12 Read/Write 0h
Color (COL): This field indicates the color of the
physical jack for use by software. The color for
an internal connection is Unknown.
11:8 Read/Write 0h
Miscellaneous (MISC): No PDC override.
7:4 Read/Write 3h
Default Association (DA): This field is used by
software to group Pin Complex (and therefore
jacks) together into functional blocks to support
multichannel operation. All jacks with the same
association number may be assumed to be
grouped together. A value of all ‘0’s is reserved.
A value of all ‘1’s in this field indicates that the
Association has the lowest priority.
3:0 Read/Write Eh
Sequence (SEQ): This field indicates the order
of the jacks in the association group.
